code reviews are a vital part of the software development process, enhancing code quality, sharing knowledge, and fostering collaboration among team members. to ensure that code reviews are productive, here are seven strategies along with relevant code examples.

1. *establish clear guidelines*

having a set of guidelines helps reviewers know what to focus on. this can include style guidelines, architectural decisions, and performance considerations.

*example:*

```markdown
code review guidelines

1. **code style**: follow [pep 8](https://www.python.org/dev/peps/pep-0...) for python projects.
2. **documentation**: ensure all functions and classes have docstrings.
3. **testing**: each new feature should have accompanying unit tests.
4. **performance**: look for any potential performance bottlenecks.
```

2. *use checklists*

a checklist can help reviewers not miss important aspects of the code. it ensures consistency across reviews.

*example:*

```markdown
code review checklist

[ ] is the code easy to read and understand?
[ ] are there any code smells?
[ ] are unit tests written and passing?
[ ] is the code modular and reusable?
[ ] are error handling and edge cases considered?
```

3. *limit the size of the code review*

large code reviews can be overwhelming and less effective. aim for small, manageable pull requests (prs).

*example:*

instead of submitting a massive pr for a new feature:

```python
bad: large pr with multiple changes
def feature():
add a lot of code for various changes
pass
```

break it down into smaller prs:

```python
good: small prs focusing on one change
def feature_part_1():
implement part of the feature
pass

def feature_part_2():
continue with the next part
pass
```

4. *encourage constructive feedback*

reviewers should provide constructive feedback rather than just pointing out issues. this fosters a positive environment.

*example:*

```python
instead of:
"this function ...
